Benefits of technology

The solution provides reliable and long-term RF performance by maintaining consistent contact pressure, reducing user error, and preventing corrosion, while ensuring electrical isolation to preserve RF signal characteristics.

Problems solved by technology

Unfortunately, the connection that is formed may be comprised by traditional seizure mechanisms that rely upon a direct contact with a seizure screw and thus the integrity is subjective to the pressure a craft person applies when tightening the seizure screw.
For example, too little pressure on the center conductor pin can allow slight movement through vibration causing Radio Frequency (RF) impairments.
Applying too much pressure often damages the center conductor pin by scoring or denting the pin again resulting in RF signal impairments.
Hence the critical performance of the network is compromised.
Traditional seizure mechanisms are also prone to mechanical creep which allows the contact force to decrease over time.
This will result in insufficient contact pressure or movement of signal conductor.
Decreased force or contact movement results in RF signal impairments.

Abstract

A Network device includes an interface configured to be coupled to a transmission line that carries content and a content processing module. The content processing module includes circuitry configured to route content communicated via the transmission line to one or more secondary network devices. The content processing module further includes a contact assembly. The contact assembly includes an upper housing and a lower housing that define a recessed region therebetween. The contact assembly includes a screw. The head of the screw is disposed above the upper housing and the threaded portion of the screw extends through a threaded opening in the upper housing and into the recessed region. A resilient member of the contact assembly is disposed within the recessed region and has an end that is in mechanical communication with the end of the screw. The contact assembly further includes a plunger assembly. The plunger assembly is disposed below the resilient member and includes a conductive pin disposed therein that is urged by the resilient against center pin of the coaxial connector. Adjustment of the screw facilitates adjusting an amount of force applied by the pin against a center conductor of the transmission line.
